Abstract
Sensitivity to epoxiconazole of 90 single- spore isolates of Magnaporthe oryzae was determined. The EC50 values for epoxiconazole in inhibiting mycelial growth of the 90 M. oryzae isolates were 0.11- 0.86 μg/ml, with an average EC50 value of 0.260± 0.082 μg/ml. There was no correlation between sensitiv- ity to epoxiconazole and sensitivity to carbendazim or iprobenfos. In protective and curative tests, epoxiconazole applied at 200 μg/ml provided over 70 % control efficacy, while tricyclazole exhibited better protective than curative activity. The results of four field trials performed in 2010 and 2011 at two sites showed that epoxiconazole at 112.5 g a.i/ha provided over 75 % control efficacy, which was similar to tricyclazole with 300 g a.i./ha and better than carbendazim with 562.5 ga .i./ha.
